Abstract

An Improved processes for pretreating a biomass using ionic liquids to increase the accessibility of the biomass to hydrolysis and subsequent reactions such as fermentation. The pretreatment processes of the present invention overcome the recalcitrance of the biomass and produce high sugar yields. It has been found that: (1) the use of pressure increases glucose yield following hydrolysis of the pretreated biomass; (2) the use of pressure reduces temperature requirements, while increasing glucose yields; (3) the use of pressure enhances process kinetics, thereby reducing reaction times, while increasing glucose yields; (4) the use of pressure allows for the use of a co-solvent in the biomass pretreatment process, thereby reducing ionic liquid requirements and increasing loading; and (5) the use of pressure does not have an impact on the morphology or crystallinity of the biomass.
